Beam angle is simply how wide or narrow a light spreads. Imagine using a flashlight: Narrow beam angles (10°–30°) produce a focused, spotlight effect. Medium beam angles (30°–60°) offer balanced lighting for general use. Wide beam angles (60°–120° or more) spread light over a large area. Choosing the right beam angle depends on your goal:

CCT LED refers to LED lighting with Correlated Color Temperature, a scale in Kelvin (K) that measures the warmth (yellowish) or coolness (bluish) of white light, allowing you to adjust ambiance from cozy (low K, e.g., 2700K) to daylight (high K, e.g., 6500K) for different tasks and moods, enhancing versatility in homes and workplaces.
